Power Inductors for Critical Applications ST598PTA
■ Exceptionally high current carrying capability (up to
43 Amps) and very low DC resistance
■ Magnetic shielding allows high density mounting; flat wire
winding keeps the overall height to just 6 mm
Core material Ferrite
Terminations  Terminals 1 and 2: Tin-silver over tin over nickel over
phos bronze; Terminal 3: Matte tin over nickel over phos bronze.
Other terminations available at additional cost.

Ambient temperature  –55°C to +85°C with Irms current, +85°C to
+125°C with derated current
Storage temperature  Component: –55°C to +125°C.
Tape and reel packaging: –40°C to +80°C
Resistance to soldering heat  Max three 40 second reflows at
+260°C, parts cooled to room temperature between cycles
Moisture Sensitivity Level (MSL)  1 (unlimited floor life at <30°C /
85% relative humidity)
Packaging  500 per 13″ reel;  Plastic tape:  24 mm wide,
0.4 mm thick, 16 mm pocket spacing, 6.6 mm pocket depth

1. When ordering, please specify termination and testing codes.
ST598PTA103KLZ
Termination: L =Terminals 1 and 2: Tin-silver over tin over nickel over phos bronze; Terminal 3: Matte tin over nickel over phos bronze
Special order, added cost: T = All terminals: copper (95.5/4/0.5) over tin over nickel over phos bronze or
S = All terminals: non-RoHS tin-lead (63/37) over tin over nickel over phos bronze.
Testing:
Z = COTS
H = Screening per Coilcraft CP-SA-10001
N = Screening per Coilcraft CP-SA-10004
2. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc on an Agilent/HP 4284A or equivalent.
3. DCR measured on a micro-ohmmeter.
4. SRF measured using an Agilent/HP 8753D network analyzer.
5. Typical DC current at which the inductance drops the specified amount from its value without current.
6. Typical current that causes a the specified temperature rise from 25°C ambient.
7. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
